Other Parts Discussed in Thread: TL4242 I'm working on a design using the TL4242 to drive a string of LEDs via a 12" cable. The IC and the RREF resistor will be local but the LEDs will be across the cable.
My questions:
Should I build in any…
Other Parts Discussed in Thread: TL4242 Hello,
We've bought the TL4242 evaluation board to test with Wurth power leds ( datasheet - code 158353027) . Vf is 3.2V, If is 350mA, (can handle max 1A)
Testing the board with 6 leds in series mounted on a heat…

Other Parts Discussed in Thread: TL4242 Hi,
I have one question about TL4242.
In case of connecting Rrff=0.95 ohm, the constant current will be 200mA. If it occurs output short on this condition, how much flow the current?
Thanks in advance.
